LEO OLSCHEWSKI, OF'RVINGTON, NEW J'FRSEYn SPRINKLER AND ROTOR ELEIVIEN'I,THEREJiOBh Application tiled June 28,

This invention relates, generally, to 1im'- provements in sprinklers or irrigating devices; and, the present invention has reference, more particularly, to a novel and simple construction oit sprinkler, in the't'orm of a stand comprising a main stand-pipe provided with rotatably and movably disposed conveyor-members or elements, eachot Which is providedat its ree end vWithan adjustable sprinkler-nozzle, said nozzles being adapted tobe variously set, so that. the speed of rotation may bechanged to run :tast or slow, and-.also thatuthe sprinkler may be made to irrigate overa large or a small area, as may be desired; and, furthermore, to provide the stand-pipe with a novel construction of rotor or controlling element, which can be made stationary, to'prevent rotation of the sprinkler-arms, it'desired.

The present invention has for its principal objects to provide a novel and simply constructed sprinkler comprising a mainand vertically disposed stand-pipe, provided Withv a plurality or' movable conveyor-members or elements, each provided with a sprinklercap, said members or elements being rotatatably disposed with relation to each other for sprinkling` alternately an' area to the right or to the lett of the stand-pipe, or `for sprinkling at one and the 'same tinie'upon opposite sides ot' the stand-pipe, the sprinklinfaces of the sprinkler-caps being adapted tobe variously set atditi'erent angles'toy the lvertical ,axialplaneV ot the ,stand-pipe; and the conveyor-members or relements being also rotatably disposed with relation to the vertical stand-pipe, for sprinkling in any portion or an area lying` in a large or small Vsector of a circle, all YWithout having! to change the position of the sprinkler-stand, and Without any danger of becoming Wet in making the desired changes.

rlhe presentl invention has for its further object to provide a novel and simply 'constructed, as well afs aneiiciently operating sprinkler provided With sprinkler nozzles or water-heads arranged so that the elevating of one Water-head to an angle slightly above the other, causes aspray to form Within acircle, givinga complete and even irrigation to the entire areaivithin a seventy-live lfoot circle; and, furthermore, toprovide in connectionwith the device, a rotor -or controllingy element whichA is not liable to be rendered ineffective, due to deterioration caused by the LWater flowing through the same, and

which ise'asily tightened or locked', so that the revolving member of the rotor or controlling'elfement Will not turn, When suchvan arrangement of the lvarious parts is desired. y@ther objects ofthe present invention not at thistinie more, particularly enumerated will be clearly understood from the following 'detailed' description of the present invention. y The invention is clearly illustratedin the accompanying drawings, in which Figure l is a. side elevation of a sprinklerstand vshowing one embodiment of the principles ot the present invention; Figure 2 is a vertical sectional representa-tion Aof the rotor or controlling element, shown detached "from the stand-pipe, and said view being made on an enlarged scale; Figure 3' is a horizontal section of the same,l said section beingtaken on vline 3-3 in said FigureZ, and' Figure t is a view ot a Washer used With ,the rotor or controlling element, said Washer being of ak hard and` non-hygroscopro composition, such as a phenolic condensation product.

Similar characters ot' reference are employed in all of the said above described A views, to indicate corresponding parts.

Referring now to the several figures ot thedrawings, the reference-character 1 indicates, ingeneral, rone ':torin of sprinkler embodying the principles or' the present invention,y the same comprising a suitably formed base, as 2, which isl provided with a suitably constructed tubular litting 3,. to Which'may be attachechin a usual manner, a hose for conductingwater to and into said litting. This tittingA is provided with an upwardly extending outlet-member, as a, to which is attached the lower screW-tl'ireaded end-portion 6 ot a vertical stand-pipe 5, .ot any suitable length, the upper vend-portion yor saidstand-pipe being alsoprovided with a screw-thread, as 7 Mounted upon this lscreW-tln-eaded end-,portion l 7, as shown more partieularlyin Figure 6, or' the drawings,y is a union 8. i Y

The referencecharacter 9 indicates the novel rotor or controllingelement used with the sprinkler-stand, the same comprising a lower ltubular member 10 Which ifs-,externally screw-threaded, as at 11, vfor attachment yto :theunion 8, as shown in Figure lll ot' the drawings. The saidmember `10h-is also ,externally screw-threaded, kas ,at l2, 'and 'has a ,constructed outlet ,13; lAt Iaapointabove the screw-threaded portion 12, the said member 10 is formed with an annular olf-set 141, forming a seat, and with an annular projection 15 providing a suitable neck 1G. totatably seated upon said seat 1d is a. tubular rotor-element, as 17 having at its lower endportion an annular flange 18, with which is in retaining engagement, the portion 2O of a threaded thimble 19, which is internally screw-threaded, as at 21, for positioning said collar upon the screw-threaded portion 12 of the non-rotating member 10, as will be clearly evident from an inspection of said Figure 2'of the drawings. The Said rotoreleinent 17 is also externally screw-threaded, as at 22, and has an upwardly extending portion 23 which is provided with a series of holes 24, forming suitable water-outlets. The said portion 23 is also clos-ed, as at 25r` said closed end-portion 25 being provided with a stem-receiving perforation 2G.

lVithin the tubular member 10 is a spiderfranie 27, or the like, provided with a screwthreaded hole 2S for the screwing therein of the screw-threaded end-portion 30 of a stein 29, said stem extending upwardly through the perforation 26 and above the end-portion 25, said projecting portion of said stem having mounted thereon a disc or washer 31 of a hard and non-swelling non-hygroscopic material, a phenolic condensation `pro-duct being the material preferably used, and said disc or washer 31 being suitably secured in place by means of suitable lock-nuts 32 and 38.

t has been found in practice that when the said disc or washer 31 is of metal, or of other material, such as hard rubber, celluloid, or the like, that corrosion of the metal washer, or water-soaking and consequent swelling of the washer made of hard rubber, Celluloid, or analagous material, soon causes a non-rotative action of the rotatable member 17 thus defeating the main purpose of the present invention, and for that reason it has been found advisable to make the washer 31 of a hard and non-hygroscopic material, and the best material foundfor that purpose is a phenolic condensation product. From an inspection of Figure 2 of the drawings, it will clearly be evident, that with the rotor-element 17 set as show` free and unobstructed rotation of the said element 17 will be had, but that when the threaded t-himble 19 is screwed down, a binding action between the parts 18 and 20 will be had, so thatthe rotor-element 17 will lbe positively locked against rotation. c

As will be understood from an inspection of Figure 1 of the drawings. the water-discharging end-member 23 of the rotor-element 17 extends into a T-tting 134-, which is suitably screwed upon the screw-threaded portion 22, as shown, so as to rotate with the said element 17. Extending laterally from said T-fitting 34 is a tubular member 35, 3rovided at its free end with an internally screw-threaded receiving socket 36,V into which is screwed a nipple 37. Suitably sc 'ewed upon this nipple 37 is a union, as 88, with which is suitably and rotatably connected the end-portion l0 of an elbow 3Q, into the free end-portion of which is screwed the screw-threaded portion of a sprinklercap 11, said cap being` provided in its convexly formed end-wall 1-2 with a series of openings or perforations 13, preferably extending in a single line diametrically across the surface of the said end-wall. Y nected with the previously mentioned T-titting 3ais a screw-tln'eaded nipple 4:4, upon which is screwed a union 15. Connected with this union 45 is the end-portion 17 of another laterally extending .tubular member 16, provided at its free end-portion with an internally screw-threaded receiving socket 18. Suitably screwed into this socket 18 is another nipple 49, and screwed upon this nipple is a union 50, with which is suitably and rotatably connected the end-portion 52 of an elbow 51, into the free end-portion of which is screwed the screw-threaded portion of a sprinkler-cap 53, said cap being also provided in its convexly formed end-wall wit-h a. series of openings or perforations preferably extending in a single line diainetrically across the surface of the said endwall.

The operation of the sprinkler-device will be clearly understood from the foregoing dcscription of the invention. It will be evident that by variously setting the sprinklerheads or nozzles at different angles, the sprinkler-arms can be made to revolve at lany speed, so as to cause the device to irrigate over a large kor a small area. The arrangement of theperforations in the sprinrler-liead is such, that the streams of water from each sprinkler-head break into a, mistlike cloud, which settles upon the lawn or plants like a heavy dew, thus assuring perfeet watering, preventing' breakage of delicate plants, and causing the water to penetrate the earth, rather than forming in puddles.

y Of course, it will be understood that the number of such outlet members or elements may be decreased or increased, without departing from the scope of the present invention.

I claim .1. A rotor-element for sprinklers, comprising a lower tubular member, a tubular rotor-member, said rotor-member having an end-wall provided with a perforation, and said rotor-member being further, provided with discharge-orifices, means connected with said lower tubular member for rotatably mounting said rotor-member uponfsaid lower tabular member, a stem within said Also conlll() lower member and said rotor-member, said stem having a portion extending through the perforation in the end-wall ot said rotormember, a disc ot phenolic condensation product mounted upon that portion ot the stem extending from the end-wall ot the rotor-member and against Which said endwall is adapted to rotate, and meansupon said stem tor maintaining said dise in its position upon the projecting end-portion of said stem.
